+# # I maintain this because:
+# Parabola version patch script does not apply consistently
+# Parabola version lacks ath9k and greysky2 patches
+# Parabola version allows SM3 and SM4
+# Parabola version is 300 Hz
+# Parabola version supports Intel ME
+# Parabola version is not configured for openrc
+# Parabola version builds docs using python and graphviz
+# Parabola version is out-of-date
+# Parabola version disables modules for components that lack free firmware
